It's one of those ill thought out ideas that came from the question they obviously posed themselves in WGT HQ, "How can we sell as many of these new CC passes as possible, as quick as possible?"
Along with CC Clashes, Golden Putters, Gnomes, Superpasses. Everything is(was?) so much geared towards squeezing your wallet rather than enhancing the gaming experience it's quite sad.
They should cap the CC levels at 20 while they still have a way of rescuing that situation. Leaving it open ended will make more sales though so the farce will continue.
